Edward Adam Davis 12f58dce48 wifi: cfg80211: fix RCU dereference in __cfg80211_bss_update 
[ Upstream commit 1184950e341c11b6f82bc5b59564411d9537ab27 ]

Replace rcu_dereference() with rcu_access_pointer() since we hold
the lock here (and aren't in an RCU critical section).

Fixes: 32af9a9e1069 ("wifi: cfg80211: free beacon_ies when overridden from hidden BSS")
